Unless Republicans are willing to show some flexibility in their insistence on purity from each of their candidates, the splitting that is increasingly evident will tear the party apart even as it faces the most serious challenge from the Democrats in years.
The Democratic debate last night was a demonstration of Bar ack Obama's limited ability to project issues. He managed to sit through a debate over bankruptcy without citing Hillary Clinton's massive campaign contributions from banks and lenders.
In a series of exchanges on subprime mortgages, he didn't mention her contributions from precisely the companies that pushed these flawed lending instruments. He even failed to mention the $10 million the Clinton library got from the Saudi monarchy even when asked about American banks going to that family for capital infusions.
We need less rancor among Republicans and sharper issue distinctions among the Democrats.
