Ramesh Ponnuru points out that Libertarian
presidential candidate Bob Barr voted for the Medicare prescription
drug entitlement, which John McCain voted against, and to authorize
the use of force against Iraq despite running on an antiwar
platform. He might as well have brought up Barr’s vote for the
Patriot Act and record on the drug war. When it comes to
third-party candidates with little or no chance of actually being
elected, I’m less concerned about their past records than I am with
their current platforms: While you have to worry about how a
major-party candidate might actually govern, a vote for a
third-party is a vote to make a statement. As long as the
electorate and the media generally associate the candidate with his
platform, then a vote for that candidate strikes me as making a
statement on behalf of that platform.
Many people are not likely to see things this way. Unfortunately
for Barr, one such group of people might be the Libertarian Party,
which frequently prefers philosophical consistency to electoral
viability (a significant minority of Libertarians found Ron Paul
too conventionally conservative in 1988). Given the party’s
ideological and educational mission, Libertarians do have a
legitimate interest in ensuring that their nominee is small-l
libertarian. As I’ve observed on the main site, Barr’s shifting
positions might make him the Mitt Romney of the LP.
The second group of people who might object to inconsistencies
in Barr’s record are the disaffected hardline conservatives he
would need in the general election if he became the Libertarian
nominee. Barr, like McCain and the Republicans, may feel that these
people have nowhere else to go. But right-wingers who want a
presidential candidate who opposed the Iraq war, the prescription
drug benefit, and the Patriot Act at the time might prefer
Constitution Party nominee Chuck Baldwin.
UPDATE: As Phil, Ponnuru, and Clark Stooksbury point out, Barr
voted for a prescription drug bill but the Bush plan actually
passed after Barr left Congress. But Barr voted for an entitlement
expansion nonetheless.
