Twitter is especially effective. Senators do not know what area of the country you are from. They cannot ignore you like they can w/email or phone calls.
Use this group to copy/paste into a tweet with a short message before the names. In that way you can tweet the whole group in a short time. Example below uses eight names at a time. You then just repeat using the next eight until you have worked thru the whole list.
NO on gun control! @SenateDems @tammybaldwin @MaxBaucus @SenatorBegich @SenBennetCO @SenBlumenthal @SenatorBoxer @SenSherrodBrown
My method is a very short message that allows for many Senators at a time. What is important is that they be continually innundated with what We The People demand. Let them give the long speeches, I just want to get the message in!
