3) Pinal County Sheriff Paul Babeu is forming an exploratory committee today to run as a Republican in Arizona's newly-drawn 4th District. The expansive western district is technically unclaimed - freshman GOP Rep. Dave Schweikert lives on the border of the district, but has indicated he'll run in the Scottsdale-based 6th District, where he'd likely face Rep. Ben Quayle, R-Ariz. GOP Rep. Paul Gosar could still run in this more GOP-friendly district instead of his current 1st District against former Democratic Rep. Ann Kirkpatrick, but he hasn't' indicated he's considering such a move. The new 4th is solidly Republican, voting 64 percent for home-state GOP Sen. John McCain for president in 2008. "It's clear that Washington is broken. To fix it we'll need leaders unafraid to make tough decisions, leaders more worried about the next generation than the next election," Babeu will say in a release later today. "I believe it may be time for a new Sheriff in Washington." 2) Nevada yielded to pressure from New Hampshire and the RNC and will hold its caucuses on Feb. 4. It's good news for the Granite State, and Secretary of State Bill Gardner, who can now be happy with a Jan. 10 primary. It is also good news for Romney, who was in between a rock and a hard place in the tussle between two states in which he's expected to do well. Meanwhile, Romney will get a notable nod today in the Granite State: Former Gov. John H. Sununu will endorse the former Bay State governor. 1) What to do when your jobs plan isn't going anywhere in Congress?
