The latest Quinnipiac polls show Barack Obama building significant leads over John McCain in three key swing states, Pennsylvania, Ohio and Florida, notes Jerome Armstrong. Obama’s surge is due to voters liking John McCain less and trusting Obama more on the economy, Armstrong notes. McCain, in a testy meeting with the Des Moines Register’s editorial board, stridely denied that his campaign hasn’t been fully honest but sounded like he could soon become “unhinged,” writes Todd Beeton.
