GRAND JUNCTION, Colorado (CNN) - As the presidential campaigns enter their final days, Alaska Gov. Sarah Palin is getting getting the rock star treatment, drawing much bigger crowds than her running mate, Sen. John McCain.
But it's still a mystery whether the "Palin factor" will drive enough conservatives to the polls to offset Sen. Barack Obama's gains with independent voters.
During her stops in battleground states, Palin, the Republican vice presidential nominee, has continued her role as the main attack dog.
She continues to rip into the Democratic ticket, suggesting that Obama and Sen. Joe Biden's plan to raise the taxes of those making over $250,000 smacks of "socialism."
"Barack Obama calls it 'spreading the wealth.' Joe Biden calls higher taxes patriotic. Joe the plumber said it sounded to him like socialism. And now is not the time to experiment with that," Palin said during a rally Monday in Grand Junction, Colorado.
Rank-and-file Republicans are digging her feistiness, but many question whether she can draws voters outside of her party's conservative base.
