On Tuesday's post-Indiana and North Carolina primary coverage, Chris Matthews ranted about talk show host Rush Limbaugh's plea to conservatives and Republicans to vote for Sen. Hillary Clinton in an attempt to prolong the battle for the Democratic presidential nomination between her and Sen. Barack Obama. Here's what Chris had to say:"I have to offer a Keith-style special comment on that. Anyone who voted to screw up the political system of this country with the purpose of mischief should carry that with them the rest their lives. What a ridiculous way to use the vote for which people fought and died, to use that vote to make mischief. I hope you're proud of yourself."
