So? The purpose of IRV is only partially to help out 3rd parties... Moreso, it's to get a more accurate depiction of the people's views. If, for example, in the 2008 election(supposing IRV was instituted at that time):
Percentage of people Party
1ST CHOICE
35% Democrat
35% Republican
2ND CHOICE
15% Libertarian
15% Green Party
If people voted this way, then it would be clear that the Democrats should, if they want to attract more Green/Libertarian votes when it comes to voting for your PRIMARY choice, introduce some degree of green and or libertarian-leaning legislation or something. The point is, under a system like this, it would give minority parties in the country SOME voice, rather than none..
Likewise, if the Republicans looked at this, they would realize, if they wanted to attract some green/libertarian votes, they may wish to follow a more libertarian/republican policy than the one they were doing previously.
In other words, helping 3rd parties is only half of it.. the extra benefit is that it gives smaller parties some influence, rather than none, in policy. (And they should have /some/ influence, not none, as people deserve to be represented, no?)
Likewise, since it is a democratic system, the amount of influence they would have over the PRIMARY parties would be dependent upon the number of secondary votes the corresponding secondary parties recieved.
