Mr. Lal Kantha's answer was incorrect. JVP never campaigned for or against Elam in General Election under CBK. There were no victories to govt on war at that time but some significant defeats read .https://en.wikipedia.org/wiki/2000_Sri_Lankan_parliamentary_election
Even economy was in bad shape with minus growth for the first time in Independent SL
Without JVP People's Alliance could not form a govt and they supported her govt and were given three ministerial posts too.
This is how JVP fool people (same way GR did ). People who remember year 2000 may know why JVP supported CBK who vowed to abolish executive presidency in 1994 did not do so once she got appointed with 62.4% of votes!! Despite this JVP supported CBK for war efforts ? A joke
