Romney holds a comfortable lead over Rick Santorum going into Tuesday’s primary election. Wisconsin does not have the profile of a state that is Santorum-friendly. I saw a graphic on TV on Friday showing that the percentage of voters who are evangelicals is much smaller in Wisconsin than in Ohio, and Santorum didn’t do well in Ohio. In any event, Romney’s biggest threat isn’t Rick Santorum. It’s Mitt Romney. Folks don’t like him. From the Washington Post: A recent (March 14-18) Washington Post-ABC News poll was conducted by telephone among a random national sample of 1,004 adults, including users of both conventional and cellular phones. The results from the full survey have a margin of sampling error of plus or minus 3.5 percentage points. The results: 50% of adults and 52% of registered voters view Romney unfavorably. The Post said this was the worst number for a leading presidential candidate since 1984, when Ronald Reagan won every state against Walter Mondale except Mondale’s home state of Minnesota. The obvious danger for Republicans is that Romney’s high unfavorable rating jeopardizes the GOP’s effort to protect, much less extend, its majority in the U.S. House of Representatives, and to wrest the Senate majority from Democrats. I’m sure everybody is tired of hearing about a brokered convention, but if Romney goes into the convention with these numbers, will party honchos start looking around for an alternative? These developments indicate how prescient George Will was when he wrote recently that Republicans should focus on what was attainable–that is, taking back the Senate majority from the Democrats and increasing the Republican majority in the House–instead of trying to defeat Obama.But are those scaled-down goals attainable with Romney as the party’s standardbearer? And if not Romney, then who? Suppose Romney’s numbers continue to tank. Does this resuscitate the possibility of a brokered convention?
