In the US, is it at all worthwhile to write/call a Senator or Representative about a legislative issue? Is it likely to have any effect at all?
I suspect it's a useless endeavor because of several reasons. In the case of one elected individual, who is of an opposing political viewpoint, wouldn't they just write me off as someone who didn't vote for them to begin with (and so they risk nothing by ignoring me). In the case of another, I already know from their voting history that they would likely agree with me on the same issue. So I wouldn't be changing anyone's mind if I wrote them anyways. Also, I'm but one tiny voice in a large constituency.
Do voters who are unenrolled possibly have a tad more influence because the Sen. or Rep. might view them as a "swing" voter who could be wooed?
