The Republicans used to routinely win Presidential elections. Now the party will have to have a fundamental rethink if it is to win again. The central key to Republican dominance a generation ago was race and demography. The same factors are now the key barrier to the party winning again.
The race for the White House in 2012 offers a striking example of a major western election in which a party has destroyed its own prospects of power by going too tough on immigration, by being perceived to adopt so hard a tone on the issue that it has toxified the party brand, particularly with Hispanic voters, who are the fastest-growing section of the electorate, but also with voters under 35 more generally, particularly graduates.
