The Hill by Cameron Joseph.  Sen. Mark Begich (D-Alaska) is going local in a bid to save his seat in the Senate — and possibly the Democratic majority in the Senate.   The first-term senator is touting his stances against the federal government in an effort to emphasize what he says are his Alaska-first policies.  After Sen. Mark Pryor (D-Ark.), Begich is seen as the most vulnerable Senate Democrat running for reelection next year, and Republican chances of winning the six seats needed to retake the Senate would improve substantially if he loses.  To avoid that fate, the Alaskan is highlighting his support for the state's fishing and oil-and-gas industries and work on military and native issues.
