To win a primary you only have to edge out your competition. You could win with 20% of the vote if your opponents only had 19%.
To win a general you need to win the Independents. The lever pullers for the Red Team and Blue Team will not change their vote no matter what the candidate's record or platform. Win the swing voters and you win the election.
Does Newt have what it takes? Do enough Republicans believe his rhetoric? Can he draw in the Independents with that record of his? Time will tell.
Newt has good points and bad points, just like every other candidate.
He understands policies and issues better than anyone. He can get some things done. Many of your criticisms of him are justified. That doesn't disqualify him.
If you just want to talk baseball, okay. Newt's strengths are that he's experienced, he has command of the issues, he's a good debater, and he appeals to the conservative base, including the social conservatives. He's not anyone's best pick, but he's got a lot of positives, mostly in the primary.
In the general he has two major problems. One, the independents don't like his existing negatives, though he's tried to soften that over the years.
The other problem is that the press will kill him, and dredge up lots of things from the past. He's easy to vilify in the general.
Personally, I like that he's smart, he has a command of the issues, he'd destroy Obama in a debate, and he's probably the best sound bite generator of the bunch. I also think in his heart of hearts (and of course this is just conjecture on my part) he's relatively fiscally conservative, though he's a whore like all of them are, and has a record of jumping around.
But most of that is irrelevant, for as I've wasted many electronic bytes explaining, either a Democrat or a Republican is going to be the next President and the party they belong to is much more important than their individual attributes, because like it or not, that's how our system works.
There.
