I meant where obama has higher value compared to other candidates. Looking at
the column NY, Obama has the highest. So to state that he wins. Looking for
AR column, Michelle wins. I JUST want to list where obama wins.
Thank you! This seems to work, just do not understand why you used a
threshold?

The criteria is to list where Obama has a higher number of contributions. The
table shows the number of contribution that each presidential candidate
received in a state of the country.
The table shown is an example, the query should be generic to a database

To take this example I reduced the number of records absurdly. In the
original database there are 48 000 candidates and dozens of states. There is
no way to analyze data visually. I would not put 400 mb of tables here. But
based on the example how could list the states where obama received more

I believe that previously could not be understood. To facilitate'll give you
an example. Assuming my table is presented below with the amount received
from each candidate for president in a particular country state.
