Over the past few weeks, my $2.50 gas plan has shown how America could have cheaper gas, more jobs and greater national security while putting the White House on the defense over their anti-American energy policies. This is the type of leadership I can offer as the nominee, and this campaign will spend between now and when the delegates vote in Tampa relentlessly taking the fight to President Obama to make this case."

Mitt Romney is a joke just like the rest of these candidates...he is a Wall Street guy and that clearly means that he will be saying one thing while clearly thinking another...which is to say that he cannot be trusted. HAS ANYONE SEEN "WHEN MITT ROMNEY CAME TO TOWN"??? He only knows what is best for him, not the average American family.
The view from the outside (Canada) is very disappointing. Once again, we are treated to seeing just how many votes money can buy. LOTS. I would have thought that the obvious warning for the average American was when all the super rich eagerly lined up to oink for their fellow old boy Romney. They are right now gathered around the huge feeding trough waiting for him to get voted in so he can fill 'er up! These are the same rich people who if it would earn them five extra cents would send every penny of theirs to China and meanwhile curse the locals (Romney joined right in on this eg. Auto sector). If the super rich feel the local unions are ruining Amercian free enterprise; wait till they see what the Chinese have in mind! Romney's buddies are greasing the wheels of the Oriental Express intended to derail America. Of course, they'll just get richer and fatter so I guess that works out for them. I wonder where all the widespread sentiment and energy has dissipated to that cheered the crowds that demanded that the 1% be called to task. Well, right now they are apparently allowing a barrage of television ads to sway them to blindly voting the 1% King onto the throne. Mind you, this all doesn't affect me... I get to sit back and just watch... but I can't help but be disappointed in the American Political Theatre. It all just looks like either a 'Bush' or 'Son of Bush' rerun. Yawn. I wonder what's on the other channel right now...
Mitt Romney is like lukewarm water - you just want to spit him out of your mouth. He has no passion. His words inspire no one. He believes he can solve the problems of this country by simply playing the numbers and doing the math. What a sad day in America.
Santorum lost his edge when he traded in himself - his life's example - for being the king, spokesman and legistator of righteousness.
Blue and union rich illinois will never ever vote a repube president into the whitehouse. GO OBAMA/BIDEN 2012
Brian T's logic is skewed. Romney will take red states come November, no question. The fact that he's taking a whole lot of independents/moderates with him now shows that he has the capacity to challenge the lock candidate Obama had on wedge independent voters in states like Ohio, Penn, Michigan in 2008. Illinois will be a bridge too far but is indicative of a strong campaign on the part of Romney.
Romney at my alma mater. Santorum in the city where I live. Thank goodness I'm out of town right now.
Doesn't matter, though. Illinois is blue and will stay blue, regardless of what the Downstate trogs think.
Go Go Mitt Romney who can save America!!! Obama are going broken Ameica and debts 16.5 trillions?? If keep going up up 30 trillions in 2013 to 2016 debts our dollars will be worthless!! Obama want increase gas 10 dollar per galllon! his dream in four year ago and crazy that who vote or Obama?? Vote for Mitt who can beat Obama!! . Awake up Vote for Mitt will back around and save America!! GO GO Mitt 2012!!
To Packersfans: President Obama does not set the gas prices...OPEC does and the global market...that gas price arguement is such a misconception...don't base your votes on misinformation. It is too east to place all of America's problems on one person and that just isn't the truth.
Newts hanging around like old dirty smelly laundry but after he quits he'll take that Calissa back to Tiffany's from all the money he earns. Goodbye Newt, you are what a historian would call a part of "bad history".
