With the Republican Party now having the majority in both the House and Senate there wouldn't be concerns about vetoes as there are with a Democrat in office. As it is now it doesn't matter what legislation republicans pass because Obama can veto it and they don't have 2/3rd majority to overturn his vetoes. Basically having a majority in the House and Senate doesn't matter too much.
But here's the huge thing and that is the use of Executive Actions/Powers. President Obama has issued 202 of these (as of this post) so the President can make things happen by bypassing the Legislature. Keep in mind the people in the House and Senate are supposed to be representing their constituents so when a President does this he's basically not letting our opinions matter. I don't believe in Actions and Orders being used the way they are as it goes against what our Forefathers put together in creating a balance of powers in the Federal Government. One thing I promise you and that is Democrats will do everything they can to limit the authority of Executive Orders even though they've loved using it over the last seven years.
The bottom line is your vote does matter in the upcoming Presidential Election. Things have changed in many ways because of these powers and in a partisan world it is a huge advantage. Please not only get out to vote but drag as many voters with you (as long as they're republicans). Help them understand that our choice for President can make or break our country and the philosohy and values we believe in.
