http://news.yahoo.com/s/ap/20110113/ap_on_re_us/us_congresswoman_shot_palinWith her video defending herself against critics — in which she accused them of "blood libel" — Sarah Palin again showed she is weighing a presidential bid in unprecedented and even daring ways.
The former Alaska governor commands nationwide attention with her selective use of Facebook and Twitter, choosing provocative words when others testing the presidential waters prefer a lighter touch.
Some political pros say her tactics, which protect her from mainstream reporters and neutral audiences, are savvy and effective. Others say she will have to change if she hopes to win the crucial Iowa caucus or New Hampshire primary, let alone the 2012 general election. Many agree she's a master at exploiting the campaign possibilities of fast-changing social media.
Palin was bound to be drawn into the national debate that followed Saturday's shooting rampage in Arizona, which killed six people and gravely wounded Democratic Rep. Gabrielle Giffords. Last March, Giffords noted in a TV interview that Palin's political committee had targeted her district, among others, with crosshairs. "There are consequences to that action," Giffords warned.
