Saw your message for Split ticket voting couldn't really find a resource for it I learnt it from my textbook it is not really that hard
For example if there is a question like Why do some voters split their ticket when voting in US elections and what are the
consequences of such behaviour? (30 marks)
You would first define split ticket voting: They may note the paradoxical nature of STV as some voters are
apparently voting for two different parties on the same ballot paper at the same election
Then you would reasons why they use STV
1) Issue voting - Many candidates vote for candidates due to the issue. This is a reason why they use STV. For example in 2004 many Catholitcs voted for Bush (52%) You can also find other examples e.g. due to the big tent system many voters will not be fully aligned to their party e.g. someone who is a Moderate Republican living in Maine may vote for a Democratic candidate because they believe in e.g. big spending, pro choice etc... Likewise same can be argued for a Conservative Democratic e.g. In the South they may have voted for Mccain in 2008 perhaps due to his policies on economy , small government spending etc... Synoptic link many people in UK vote on issues e.g. 2010 election many voted Cameron due to his economic policies
2) Candidate centred issue - many of the voting is candidate centred. Always use this two examples to get you the highest marks. Obama in 2008 and Reagan in 1980 and 1984. 19% of Republicans used STV for Obama while 55% of Democrats STV for Reagan in 1980 and 1984. This is due to the fact they like their policies and what they have to offer many STV for Obama due to him being the better candidate than Mccain and being more charismatic while in 1980 and 1984 many Democrats liked Reagans economic rules and he was seen as very approachable.
3) You can also argue that many people STV for the incumbency factor. This is the idea that many vote for their HOuse of represenatives because of the pork barelling and benefit they get for their state. For example the candidate will increase their spending on the state e..g education, transport etc... Therefore thats why a voter will use STV because they want to keep that same person to gain the benefits for their states.
Finally consequences are divided government which has risen and this can lead to gridlock e.g. Clinton 1999 and Bush 2001 who had problems passing his education bills I think. However you can argue that you get a more stable government compared to the UK where executive dominance can lead to tyranny but strong divided government leads to less tyranny in the USA which the FF intended this helps avoid the whims of the day.
Another consequence is gaining the best of both worlds someone may benefit by their democrat congress e.g. providing healthcare and education due to inherent powers they have while they gain by their republican president say via lower taxes.
Conclusion: It is a very unique way very different from UK where we have straight ticket voting but it leads to more choice in the hope that more people vote however this does not always happen but you can argue that we have a more accountable government compared to the UK
Hope that helps if not read the mark scheme in more detail and I hope you do well
