Rudy will not keep the base close. They base hates Rudy almost as much as Hillary, and his only hope is that our hatred of democrats is more.
Any liberal throws liberal states into play against Hillary, if you assume republicans will vote for him.
If Joe Leiberman ran as a republican, he'd trounce Hillary in the general election -- IF all the republicans still voted for him.
There is a reason we have primaries and don't let the general population pick our candidate -- because we'd end up with centrists that oppose what we believe in.
The Rudy supporters are trying to use opinion polls to replace our primaries in order to allow the democrats to pick our party nominee.
Sort of like the Democrats all got stampeded into picking J.F. Kerry in 2004 because opinion polls showed he could beat Bush before people knew anything about him other than his Viet Nam resume. We all know how that turned out, don't we?
Sorry but the base does not hate Rudy. You might and many on this forum might. However, there are many prolife conservatives that support Rudy and would support another candidate if the base so chooses. How about hmmm lets have primaries and let the base decide who they want as the nominee.
