(CNN) — With less than a week to go until the critical primaries in Indiana and North Carolina, it's getting close to crunch time for Sens. Hillary Clinton and Barack Obama.

In the latest episode of CNN=Politics Daily, Jessica Yellin reports on how Clinton and Obama are courting blue collar voters in Indiana and courting their party's superdelegates.

In an effort to dissuade the so-called "Reagan Democrats" from choosing Sen. John McCain in the general election, unions in several key states have already begun to target the Republican Party's presumptive nominee. Chief National Correspondent John King is out on the campaign trail with McCain. King explains what the unions are up to and what McCain intends to do to court a key group which both he and the Democrats will likely need to win the White House.

As Clinton and Obama continue to battle it out in the remaining primaries, their party has yet to resolve how to handle the delegations of Florida and Michigan — two states who held their primaries in violation of the Democratic National Committee's rules and were punished by being stripped of all their delegates to the nominating convention. Senior Political Analyst Bill Schneider reports on a new proposal by Michigan's congressional delegation to apportion the state's delegates between Clinton and Obama and allow the state's delegation to participate in the convention.

Clinton, Obama, and McCain have been trading barbs lately over who has the best plan to tackle rising gas prices. Dan Lothian reports on the proposals of the three candidates.

Finally, a union leader in Indiana gave Sen. Clinton an unusual introduction Wednesday. Watch Clinton be complimented for her "fortitude."
