Reagan won NH in 1980, getting an absolute majority of the vote in a crowded foeld that included Bush.
One problem with NH is that within a 24-year period as of 2012, it will have only voted Republican for President twice (1988 & 2000).
The results were Iowa picked the winner two of four times (1996 and 2000) and rejected the winner both times in the general election balloting.
New Hampshire also picked the winner two of four times (1980 and 2008) and rejected the winner one of these times in the general election.
Not at all an impressive track record for the two states which get a lopsided amount of attention in selecting presidential candidates . . .
