I like Chris Christie. He's moderate, he says what he thinks without censoring himself, he has a good sense of humor, and a lot of Republicans BEGGED him to run this time, but he said it wasn't in him right now. I don't think this particular "reaching across the aisle" is anything that different from what he's done in the past, and he's already had people hoping that by the next election he'll be ready and willing to run. He's been on the radar as a presidential hopeful for a long time now, since the Republican debates summer before last, when everyone realized what a sorry group of nut jobs and underwhelming candidates the Republicans had to choose from for the 2012 election.
The Republican party needs someone to make them seem more appealing to a wider range of people, otherwise they can just continue to fall apart and become largely unimportant. People were complaining that Romney was too moderate and that was the problem. Um, no. It's the other way around, I think.
