The chart compares prospective voter support leading up to the 2012 presidential election. this chart demonstrates that more men were likely to be liberal voters. more men were likely to be progressive voters. more men were likely to be democratic voters. more men were likely to be conservative voters.

        The chart, demonstrating that most men in October 2012 supported the candidate Mitt Romney implies an inclination on conservative views. The candidate, from the Republican party, expressed in his campaign propositions  that favored conservatism such as maintaining the operation of Guantanamo Bay Camp,  repealing the Patient Protection and Affordable Care Act, opposing mandatory reducing of greenhouse gases, and opposing same-sex marriage.

         As the chart suggest, the election was very competitive, with Democratic candidate Barack Obama winning in a rate of  51.1% against 47.2% to Mitt.

the underground railroad (apocope of the metropolitan railroad) is a system of urban trains located within a city and its metropolitan area. it is characterized for being a massive transport of passengers in the big cities, uniting diverse zones and their environs, with high capacity and frequency and in segregated form to other systems of transport. metropolitan railroads are built underground or on the surface, although most systems use mixed models where sections are combined in both modalities.

1 - as a result, the metro tends to reduce car travel for two reasons: first, due to the greater transfer of users from the car and, second, due to the reduction in the acquisition of cars in homes located in sectors near the stations of the metro.

2 -the metro allows to contribute effectively to the achievement of all the objectives of an urban development policy: it improves the efficiency of the city's economy by reducing travel costs and also generates a higher level of activities in the city center, taking advantage of of the agglomeration economies.

3 -it is a clean means of transport, since it uses renewable energy (usually electricity), taking care of the environment and avoiding excessive pollution.
