WASHINGTON (AP) - There's not much political mystery about the eight senators who crossed party lines in Wednesday's showdown vote on background checks for gun buyers.
The four Democrats who voted against broader background checks are from largely rural states that voted heavily against President Barack Obama last fall. Three of them face tough re-election battles next year.
Three of the four Republicans who voted for the measure are from states Obama carried easily.
The four Democrats who angered Obama are Sens. Max Baucus of Montana, Mark Begich of Alaska, Heidi Heitkamp of North Dakota and Mark Pryor of Arkansas.
Campaign strategists say they must appeal to conservative and centrist voters in their states to stay in office. Rural voters support gun rights more so than urban voters.
