(CNN) - White voters continue to support the Republican presidential candidate, as they have for many years. In the exit polls reported thus far tonight, 53 percent of whites say they voted for McCain while 43 percent of whites voted for Obama.

Obama, however, has a dramatic edge among African-Americans (96 percent), Latinos (67 percent ) and Asians (63 percent). Significantly, America's non-white vote is increasing as a proportion of the entire electorate. In the 1992 presidential election, whites made up 87 percent of all voters. This proportion fell to 83 percent in 1996; to 81 percent in 2000 and 77 percent in 2004. So far in today's exit polling, whites make up 75 percent of the electorate. Projected demographic trends indicate that the proportion of non-white voters, particularly Hispanics, will increase further in the future.

Exit polling also shows that McCain winning among Southern whites by a margin of 69 percent to 31 percent. Outside the South, McCain won among white voters 51 percent to 49 percent.

Obama's race boosted his results.

(CNN) - So, did race play a role? Yes, but it worked in Obama's favor.

About 20 percent of voters said race was important in how they voted, and those people voted for Obama by an 11-point margin, 55 percent to 44 percent. That means more people voted for Obama because of his race than against him. So much for the "Bradley effect."

And of the 80 percent of voters who said race was not a factor in their decision voted nearly the same way, breaking for Obama 53 percent to 45 percent. That means race played a role, but it was not a decisive factor.

(CNN) - Early exit polling shows voters expect a post-election tax increase. Forty-nine percent think their taxes will go up no matter who is elected president. Twenty two percent say taxes will go up only if Obama wins. Twelve percent say taxes will go up only if McCain wins. Only 15 percent say their taxes will stay the same or go down.

(CNN) – Sixty-two percent of voters polled Tuesday said the economy was their top election concern, according to early national exit polling.

It was far ahead of the second-place issue, the Iraq war, which was named as the top concern of 10 percent of voters polled.

Those who picked the Iraq war as their top issue mostly voted for Sen. Barack Obama in all but two states, according to the early exit polling results.

Health care and terrorism were tied at 9 percent as the issue voters were most concerned about, according to the exit polling. Those who picked terrorism as their top concern overwhelmingly choose Sen. John McCain, according to exit polling.

For the exit poll, voters were selected at random to fill out questionnaires after voting.

Hillary Clinton gets a boost from voters economic concerns Tuesday.

(CNN) - The economy is the No. 1 issue among Pennsylvania Democrats, just as it has been in nearly every other primary state. Close to 55 percent of voters there rank it the top issue, while 28 percent say the Iraq war is their top concern.

Hillary Clinton is the clear beneficiary - she's winning 56 percent of voters who are worried about the economy, while Obama wins 43 percent of those voters.

Competing political signs are seen in Philadelphia.

(CNN) - Hillary Clinton and Barack Obama are both holding strong among the most reliable members of their base.

Obama is winning 92 percent of black voters, among his highest margin to date in that demographic. Meanwhile, Clinton is winning among voters 65 and over by a 23 point margin, 61 to 38 percent.

Both candidates have held on to their base, a sign the trench warfare of the last four months could continue.

Dems picked McCain over Romney, but few participated in the GOP primary.

WASHINGTON (CNN) - Despite urging from some activists like Daily Kos' Markos Moulitsas that Michigan Democrats vote for Mitt Romney over John McCain, CNN exit polling indicates the Arizona Republican won the liberal vote.

McCain captured 41 percent of Democrats who voted in the Republican primary, 10 points more than Romney. Mike Huckabee meanwhile, only captured 14 percent of Democrats.

Though the Democratic primary race was rendered essentially meaningless after party sanctions, few Democrats decided to vote in the Republican primary - according to the exit polling, Democrats only constituted 7 percent of the vote in that contest.

Moulitsas, in an entry on his blog last Thursday entitled “Let’s have some fun in Michigan,” called on Michigan’s Democratic voters to abandon the meaningless Democratic primary and vote for Romney in the state’s binding Republican primary. By doing so, Moulitsas argued, Democrats could further muddle the Republican contest and most importantly, reduce the threat of McCain, who polls show is the biggest threat to their nominee in the head-to-head general election contest.

Though the bloggers' calls were not heeded, CNN’s Senior Political Analyst Bill Schneider points out they got what they wanted.

“The bloggers got what they wanted: Romney won. The Republican race is muddled. McCain’s momentum is halted. It’s just that the bloggers weren’t the ones who did it!," he said.
