I'd expect the sniping between the Romney and Thompson campaigns
to get worse before it gets better. They are both competing for the
same slice of voters, and they each would benefit tremendously from
the other being knocked out of the race. Thompson has the support
in the national polls and the potential to break through in the
South; Romney has solid leads in key early states and has seen some
progress in his national numbers. Their combined presence in the
race, however, is making it easier for Giuliani to lead in unlikely
places like South Carolina.
Similar competition between Pat Buchanan and Phil Gramm in
1995-96 led to the former bloodying the latter in Louisiana and
then finishing him off in Iowa. But such infighting can backfire as
well. In 2000, Steve Forbes trained a great deal of his fire on the
electorally irrelevant Gary Bauer, who peaked with 8 percent in
Iowa, while the nomination contest was turning into a Bush-McCain
race.
