A column in the Washington Times anticipates the possible spectacle of a contested Republican Convention. This being based upon the fact that there doesn't seem to be a real frontrunner, and each of the candidates could carry large numbers of delegates into the convention.
There has not been a contested presidential nomination at a convention since 1948's Republican National Convention, when Thomas Dewey finally triumphed over "The Boy Wonder of Politics" Harold E. Stassen and Robert Taft right before the 3rd ballot due to Taft's concession.
It would be interesting to see such an event, although it may mean more fragmentation within the GOP. However, having the national convention be more than a glorified coronation would be a lesson in politics for the current generation, and it would also provide infinite amounts of topics and events for us pundits.
It would also be interesting to see Fred Thompson, Rudy Giuliani, Mitt Romney, Mike Huckabee, John McCain, and even Ron Paul duke it out in a convention, especially once a candidate was eliminated...it would be very interesting to see who those delegates would support.
