When we say that Congressman vote take cues when they vote,what do we mean?

As you probably know already, cues, in this context, are the things that influence how a member of Congress votes. The order of importance will vary with the individual member, the vote, and the political realities/environment at the time. In no particular order, cues can include the following: The Congresspersons... --Principles, values, character, beliefs -- How it will benefit his constituents --Ambitions, as a Congressmember, and afterwards --The opinions of his constituents --Contributors --Other supporters, in district and out --Influential community members (other politicians, including potential competitors, business leaders, religious figures, etc.) --The media, both in-district and out, from the local paper to national talk radio hosts. --Party leadership within Congress, most directly the party whips who keep the rank and file in line. --Influential members, including those from whom the member wants assistance (votes, influence, money, etc.) in the future. --The president --The opposing party: its leadership, members and supporters --Interest groups: gun rights or gun control advocates, pro-choice or pro-life, environmental or polluting industry, etc. --Spouse, family members, friends I could think of lots more, but I'll stop there. Again, a lot of factors can determine how those cues are ranked for an individual member, and it can vary depending on the vote. For example, a member in a very competitive district has to be taking cues from his constituents, his contributors, the party leadership deciding how much to support him next election, the local newspaper writing editorials about him, and potentially many other sources of influence. A member in a district who doesn't have to fight so hard for reelection might have far less to consider, like maybe mostly his principles and the ability to raise money to help others in his party. Ultimately, cues are driven by self interest. Even the most altruistically driven politician wants to keep doing what they're doing, because that's how they can get things done for the benefit of their constituents. They will usually be principled, to a point, but they may have to compromise to advance their party, their contributors, or whomever. That's how they advance themselves, accrue more power, and get more done. It's our job as voters to make sure they're getting things done in our interest. When they don't, and we're smart, we fire them -- like what happened last Tuesday.

AS to what lobbyists are paying the most

You can't get a better or more encompassing answer than Randy R gave you.

Good answer Randy R. But YOU fired them. I did not.
